Having ridden in the jumpseat of one of Mid-Atlantic Airways' Emb-170's and looking at the cabin etc, I can say that I think this family of aircraft will most likely vault Embraer from # 4 worldwide commercial aircraft manufacturer into # 3, past Bombardier, behind Airbus and Boeing. In fact, this is a family of aircraft family that Boeing SHOULD have built. Having been inside the DC-9/MD80 family and inside the 170, I can confirm Embraers assertion that this aircraft truly does have "mainline airliner" comfort. The cabin is 6'7'' high, which is only 2 " shorter than a DC-9/MD80 and feels very spacious. Also, the seats and aisles are wider than the CRJ 700/900 family and comparable to the Airbus 320 family and Boeing 737 family. There are two spacious lavs (you could almost rent the rear lav as a room, it's so big!), and a VERY big deal for passengers, unlike the CRJ 700/900, you can actually CARRRY ON your "carry on's", instead of gate checking them. I can attest that the overhead bins will very comfortably fit an overstuffed rollaboard (sideways). Also MUCH more cargo space than the CRJ 700/900 family. The cargo bins are on the right side of the aircraft, fore and aft of the wing, like mainline aircraft. There are 4 large doors (2 forward, 2 aft) for quick boarding/de-planeing, and galley servicing. Fly-by-wire technology assures common handling characteristics among the 170, 175, 190 and 195. Range and performance are also on par or above the CRJ 700/900 throughout the family. Embraer also mentions that if an airline customer requested it, they could take a section out and create a 55-65 seater when passengers finally revolt against Embraers own cramped 145 and Bombardiers CRJ 200. Talk about having the 50-120 seat class covered! As Mid-Atlantic, Republic Airways Holdings, and next year, jetBlue begin to deploy these aircraft, along with other sure to be announced future orders, I have no doubt that the company that so many have mocked as the builder of the "jungle-jet" will be laughing all the way to the bank as Bombardier, comes to regret it's decision to stretch it's Challenger business jet even further from the CRJ 200 to the 700/900 in a "rush to market" that will remind many of Dorniers ill-fated decision to "rush to market" with an"RJ" that was nothing more than a 328 turboprop, with a couple of turbofans slapped on (who ever heard of "boots" on a "jet", other than the first generation Cessna Citation). Also for those of you who will inevitably start knocking Republic Airways Holdings (Parent of Chautauqua Airlines and Republic Airlines) for ordering 50 of these new jets, all I have to say is wait and see, as the industry changes around you. You can call us all the names in the world you want, but just wait and see as $42.00 per barrel (or higher) oil prices, increased, fierce competition from Southwest, Airtran, jetBlue, Independence Air, Ted, Song, Frontier, Spirit, USA3000, Virgin USA, etc force all of you to wake up and realize that the ECONOMY and NOTHING ELSE, now drives this industry. Southwest has been saying it and proving it for thirty years. So to all of you who will continue to knock us, I say just keep talking smack about us, as the world and industry changes around you. As even almighty Delta starts to talk bankruptcy, and efficient Continental talks about fare-hikes and furloughs, and Northwest pilots vouluntarily submit a concessions package, guess who's next? Keep talking smack about how we at REP/CHQ are the scum of the earth. Keep talking it all the way to the furlough or unemployment line (God forbid). Just get off our friggin backs! This industry has been forever changed by the low-fare airline revolution and guess what, it is NEVER going back to the old way, no matter how much smack you talk!!! This 170 family is going to continue to change the industry, and I'm glad our management had the foresight to order a bunch of them. Now, please THINK, before you reply. C YA
